Texas Instruments · DC-DC Converters · HTSSOP-14-EP
LM2852YMXAX-2.5 from Texas Instruments, in a HTSSOP-14-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AVIN | power_in | Chip bias input that powers the chip logic; connect it to the input voltage or a separate rail. |
| 2 | EN | input | Enable input: connect to ground to disable the chip, connect to AVIN or leave floating to enable it; the pin is internally pulled up. |
| 3 | SGND | power_in | Signal ground for the control circuitry. |
| 4 | SS | input | Soft-start pin: connect a small capacitor here to control startup, with the capacitance restricted to 1 nF to 50 nF. |
| 5 | NC | unconnected | No connect; must be tied to ground or left floating in the application. |
| 6 | PVIN | power_in | Input supply pin connected to the input voltage; it feeds the source of the internal power PFET. |
| 7 | PVIN | power_in | Input supply pin connected to the input voltage; it feeds the source of the internal power PFET. |
| 8 | SW | output | Switch node pin; connect to the output inductor. |
| 9 | SW | output | Switch node pin; connect to the output inductor. |
| 10 | PGND | power_in | Power ground; connect to an internal ground plane or other large ground plane. |
| 11 | PGND | power_in | Power ground; connect to an internal ground plane or other large ground plane. |
| 12 | NC | unconnected | No connect; must be tied to ground or left floating in the application. |
| 13 | NC | unconnected | No connect; must be tied to ground or left floating in the application. |
| 14 | SNS | input | Output voltage sense pin; connect it to the output voltage as close to the load as possible. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
